8. How does BHT compare to other antioxidants like Vitamin E?
BHT is a synthetic antioxidant with strong stabilization properties, whereas Vitamin E (Tocopherol) is a natural antioxidant often used in "clean beauty" formulations. Both serve similar functions, but BHT is more effective at preventing oxidation in certain formulations.
9. Is BHT environmentally friendly?
BHT is not biodegradable and can accumulate in the environment. Some cosmetic brands are shifting to plant-based antioxidants as more sustainable alternatives.
